Energy flow across a boundary system caused by temperature differences is called this.
What is heat
100
Energy is not created nor destroyed, but changes from one form to another according to this law.
What is the 1st Law of Thermodynamics
100
This type of flow is correlates to a Reynold’s number of less than 2000.
What is Laminar Flow
100
The derivative of the following with respect to x: -3x^4
What is -12x^3
100
What goes in the black box comes out of the black box, otherwise known as this principle where mass is neither created nor destroyed.
What is conservation of mass
200
At constant pressure, the temperature at which the first liquid droplet forms in a vapor.
What is the dew-point temperature
200
These types of properties are independent of the quantity of material.
What are intensive properties
200
This type of flow occurs when the velocity gradient no longer changes.
What is fully developed flow
200
The second derivative of velocity is this, not just a rude individual.
What is jerk
200
When the number of independent equations equals the number of unknown variables, the system is solvable according to this type of analysis
What is degree of freedom analysis
300
A perfectly insulated system that allows no heat to escape is considered this.
What is adiabatic
300
This type of ideal process occurs when a system returns to its original state.
What is a reversible process
300
When the operating pressure of a pump falls below the fluid’s vapor pressure, this pump condition occurs.
What is cavitation
300
The indefinite integral of the following with respect to x: e^(-3x)
What is (-1/3)*e^(-3x) + C
300
Add this type of stream to recover unreacted material and feed it back into the system at an earlier point.
What is recycle stream
400
Physical properties dependent solely on the concentration of a solute in a solvent, and not on what the solute and solvent are.
What are colligative properties
400
A process that maintains constant pressure is considered.
What is isobaric
400
The proper name of this equation which accounts for all thermal and mechanical energy effects, and is mostly used when mechanical energy dominates thermal effects.
What is Bernoulli’s equation
400
The indefinite integral of the following with respect to x: 4x^3 + sin(x) + cos(x) + x^-1
What is x^4 – cos(x) + sin(x) + ln(x) + C
400
This ratio quantifies the conversion of a given reactant to indicate the equilibrium state of the reaction.
What is fractional conversion
500
This law states that the heat evolved or absorbed in a chemical process is the same whether the process occurs in one step or several.
What is Hess’s Law
500
Named after its French engineer creator, this theoretical heat cycle operates reversibly and models the maximum thermal efficiency possible.
What is the Carnot cycle/engine
500
This law states that when a shear stress is applied to a fluid, the velocity gradient that it yields, perpendicular to the stress, is proportional to the applied shear stress.
What is Newton’s Law of Viscosity
500
The Latin word “calculus” actually means this, a common object used for counting.
What is stone/pebble
500
This equation relates vapor pressure and temperature and is essential for bubble and dew point calculations.
